We are presently using Network Associates Netshield, Groupshield, and Virusscan. It looks like pretty much the same setup you are using. What version of Groupshield are you using? I tried 4.5 but was not happy with the results when it ate up everyone's attachments. Is 5.0 Better. I have downloaded it but I have not installed it due to the possibility of changing to Norton.

Right now we are using Network Associates Total Virus Defence Suite, which include Netshield for NT/2000, Groupshield for Exchange and Virus Scan 4.5 for the Desktop PC's. I have found it to be very effective in removing/blocking/quarantining email borne virus threats, however there are some minor issues to be aware of: Netshield, although being able to download the DAT file and save them for later use, ie in a shared folder for the desktop clients using Virus Scan 4.5 to update from, a hotfix is required to be obtained from NAI to resolve the issue of Netshield not downloading the "Update.ini" file that allows the client pc's to correctly process the update of the DAT files. Once this is done we found all instances of Netshield and VirusScan4.5 updated correctly and caught all viruses, including the most recent "Bugbear" virus. Daily checks are highly recommended. Forget weekly, the DAT file version can sometimes change twice in the week. -----Original Message----- From: Stephen Hartley [mailto:shartley@xxxxxxxxxxxxxxxxx] Sent: 17 October 2002 23:31 To: [ExchangeList] Subject: [exchangelist] RE: Anti-Virus revisited
